Hello,
  Although the mlx4_hca.sys may be HW agnostic, it is not Firmware insensitive.
The mlx4_hca.sys PNP load failure was caused by the mlx4_bus driver loading in a non-operation mode due to outdated firmware.

BTW, a nice touch for your HCA customers would be to add the PSID to the event log error message so a customer would know which firmware image to download and flash!!

system Event log entries in time order (#4 is latest).

4) mlx4_bus has started in non-operational mode.

3) QUERY_FW command failed with error -19.
 The adapter card is non-functional.
 Most likely a FW problem.
 Please burn the last FW and restart the mlx4_bus driver.

2) HCA FW version 2.4.1002 is not supported. Use 2.5.0 or higher.

1)Driver Management has concluded the process to add Service mlx4_bus for
 Device Instance ID PCI\VEN_15B3&DEV_673C&SUBSYS_673C15B3&REV_A0\6&1EC6E980&0&00200030 with the following status: 0.

What I'm really curious about is why the mlx4_bus driver returned load SUCCESS (as viewed from devmgmt.msc) when indeed the event log claims the device is non-operational?

Even more curious, is the Mellanox WinOF drivers load successfully while the open-source WinOF mlx4 HCA driver never loads as MSFT PNP based on the load status of mlx4_bus claims there is no match for mlx4_hca driver??

What a tangled web....
